An evaluation of the design and analytical seismic response of a seven-story reinforced concrete frame-wall structure

This report describes the analytical studies regarding the response of a reinforced concrete test building that have been conducted at the University of California, Berkeley, as part of a US-Japan cooperative research program on the behavior of structures subjected to earthquake induced loading. This work, which begins with a review of the prototype design according to the 1979 Uniform Building Code specifications for seismic resistant buildings, shows that while the test building, a 1/5 scale model of a 7-story reinforced concrete frame-wall structure, does not satisfy all code specifications, it can be considered to be a good design from the point of view of the strong column-weak beam philosophy. The elastic properties of the structure are investigated through the use of flexibility matrices and the inelastic response of the structure to monotonically increasing lateral loads is studied.
